After spooking Trump into safety testing, Anthropic AI models get global release

US lifts curbs on Anthropic’s advanced Fable and Mythos models

The US has lifted export curbs on Anthropic’s newest Claude models, Fable 5 and Mythos 5, about three weeks after the Trump administration flagged the models as national security risks.

As of today, Anthropic confirmed in a blog post, Fable 5 will be available globally, and US organizations have had access restored to Mythos 5 since June 26.

Anthropic said it is now working with the government to expand Mythos access to a “broader set of domestic and international partners in the Glasswing program.” That program allows cybersecurity researchers at trusted companies to access Mythos for defensive purposes.

In a letter to Anthropic viewed by Reuters and The New York Times, Commerce Secretary Howard Lutnick said Anthropic would “no longer need a license for exports or in-country transfers of its Claude Mythos and Claude Fable AI models.” The letter acknowledged that Anthropic had “taken steps in close coordination with the US government to address the risks” posed by the models.

Facing a longer delay in its models’ releases, Lutnick said that Anthropic agreed to expand its partnership with the government. The company said it also set up a program to work with hackers to red-team its models, and there’s now a dedicated internal team to monitor reports of emerging jailbreak threats 24/7.

In the letter, Lutnick reminded Anthropic that the US “reserves the right to re-evaluate the decisions” and reimpose export curbs at any point.

But for now, Lutnick joined White House Chief of Staff Susie Wiles in celebrating Fable 5’s redeployment on X. “Over the past two weeks, we have worked closely with Anthropic to analyze and approve Fable 5 to ensure alignment across the US Government and strengthen America’s leadership in AI,” Lutnick said.

Wiles did not directly mention Anthropic but claimed a win for Trump, writing that “the government and private sector have worked together in a way we have never seen before and this foundation of America First is unprecedented. Our shared priority remains: get the best tech deployed as quickly and safely as possible.”
